Description
Classic French Onion Soup crafted with slowly caramelized onions, rich beef broth, and topped with melted Gruyère cheese on crusty bread, creating a comforting and elegant dish.
Ingredients
6 large yellow onions, peeled and thinly sliced
4 tablespoons unsalted butter
1 tablespoon olive oil
1 teaspoon granulated sugar
1 teaspoon kosher salt, plus more to taste
½ teaspoon black pepper, freshly ground, plus more to taste
2 cloves garlic, minced
¼ cup all-purpose flour
1 cup dry white wine or non-alcoholic white wine substitute
8 cups beef broth (low sodium preferred)
2 bay leaves
1 teaspoon fresh thyme leaves or ½ teaspoon dried thyme
1 baguette, sliced into 1-inch thick rounds
8 ounces Gruyère cheese, freshly grated
Pinch of fresh parsley, chopped for garnish (optional)
Instructions
- Prepare the onions by peeling and slicing them thinly
- In a large pot, melt butter and oil over medium-low heat. Add onions, sugar, salt and pepper. Cook slowly, stirring often, until caramelized (45-60 mins)
- Add minced garlic and cook for 1 minute. Stir in flour and cook while stirring for 2-3 minutes
- Deglaze the pot with white wine, scraping the bottom for browned bits. Cook for 2-3 minutes
- Add beef broth, bay leaves, and thyme. Simmer covered for 30 minutes, adjust seasoning
- Preheat the oven to 375°F. Toast baguette slices for 10-15 minutes
- Remove bay leaves from the soup, ladle into oven-safe bowls, top with baguette slices and Gruyère cheese
- Broil for 2-4 minutes until cheese is melted and bubbly
- Serve immediately garnished with parsley if desired
Notes
Patience is key during the caramelization of the onions; low heat develops the best flavor.
Use good quality broth for a rich taste.
